The user can input a desired sentence. When the character string predictive conversion bar 591 is selected and determined by the user's operation input at the end of the character string predicting conversion bar 591, the display is erased.

  In addition to the four-way key 26 provided on the casing 61, the information communication terminal 1 can be provided with a so-called cross key on the keyboard 71 shown in FIG. 8. In such a case, it is preferable to use the four-way key 26 and the cross key of the keyboard 71 properly.

  For example, when the up / down / left / right movement is instructed using the four-direction key 26, and the left / right movement is instructed using the cross key of the keyboard 71, the cursor movement in the editor is instructed. When a movement in the vertical direction is instructed using the cross key of the keyboard 71, it is possible to instruct selection change of a plurality of character string candidates displayed on the character string prediction conversion bar 591. it can.

  The three application softwares described above, the voice memo, the photo viewer, and the text editor, do not use communication processing with other devices. For example, regarding functions related to music content, Since there are both those that do not use communication processing and those that use communication processing with other devices, for example, by preparing a menu screen that summarizes music content handling, the user can It is preferable to be able to use a plurality of application programs that handle the above without being aware of each other.

  Communication methods with other apparatuses include a wired connection using USB and a wireless connection using WLAN. As described above, wireless connection using WLAN includes an ad hoc mode and an infrastructure mode.

  Communication in the ad hoc mode will be described with reference to FIGS.

  For example, as shown in FIG. 23, the information communication terminals 1-1 to 1-5 owned by the user A to the user E exist within the range where ad hoc communication is possible, and the information communication held by the user D It is assumed that the terminal 1-4 and the information communication terminal 1-5 owned by the user E are communicating in the ad hoc mode.

  In the information communication terminal 1, ad-hoc mode information communication terminals 1 that exist within a range where ad-hoc communication is possible are not allowed to freely transfer files or stream music data. Only when the device on the side is registered, file transfer and streaming of music data can be performed.

  Each of the information communication terminals 1-1 to 1-5 held by the user A to the user E in FIG. 23 is unique (that is, basically changed) in its own (information communication terminal 1) in the ad hoc mode. Information) and information about the current status of itself (information communication terminal 1) (that is, depending on the time) are broadcast (that is, not determined to a specific destination, but all within communication range). To the device). An example of information transmitted by the information communication terminal 1 in the ad hoc mode by broadcast is shown in FIG.

  The ad-hoc mode information communication terminal 1 has its own IP address and port number, device-specific ID, profile-set user ID, connectability information such as Busy or Ready, song name, artist name, etc. (Now Playing song) information, information necessary for stream playback when the song data is copyright protected, such as the Sequence Number + Object Handle of the song being played, other playback operation status information, etc. Broadcast information such as text memos.

  Of these, the IP address and port number of the local station, the device-specific ID, and the user ID set in the profile are basically unchanged information, the currently playing song information (Now Playing song) information, the currently playing song Information necessary for stream playback when the music data is copyright-protected and other information such as playback operation status are different information at that time, and information such as text memos entered by the user is basically It is information that can be changed when the user changes the registered contents.

  Further, the information communication terminal 1 in the ad hoc mode is described with reference to FIG. 24 as long as the information may be disclosed to a user who is not registered as a communication partner in the ad hoc mode for mutual information communication. In addition, it may be transmitted by broadcast. For example, it is an icon (thumbnail) indicating itself displayed on a standby screen (details will be described later) in the information communication terminal 1 of the communication partner in the ad hoc mode, and has not yet been registered with each other. The image data corresponding to the icon to be displayed may be transmitted to the other information communication terminal 1 in the ad hoc mode together with the information described above.

  And each of the information communication terminal 1-1 to the information communication terminal 1-5 possessed by the user A to the user E in FIG. 23 acquires information as described with reference to FIG. Whether the other information communication terminal 1 is a device held by a user registered as a communication partner in the ad hoc mode, or another information communication terminal device 1 held by a user registered as a communication partner in the ad hoc mode And the information regarding the user of other unregistered information communication terminal devices 1 that exist in a range where ad hoc communication is possible can be recognized.

  Then, the information communication terminal 1 is registered in the display unit 21 in the ad hoc mode, and the user of the other information communication terminal device 1 registered as a communication partner in the ad hoc mode and within a range where ad hoc communication is possible. An ad hoc user list display screen for displaying a list of information related to users of other information communication terminal devices 1 that are not displayed is displayed.

  In the ad hoc user list display screen, whether or not the communication status with other information communication terminal devices 1 owned by the user registered as the communication partner in the ad hoc mode is the “Online state” in which communication is possible, It is displayed as either "Offline state", which is a communication disabled state, or "Busy state", which is a communication disabled state due to communication with another device, and ad hoc communication Is displayed as “Unknown state” as the state of other unregistered information communication terminal devices 1 that exist within the possible range.

  That is, for example, when user A registers user B, user Z, user D, and user E as communication partners, the user A's ad hoc user list display screen displays the user as shown in FIG. B is online, user Z is offline, user D is communicating with other devices and busy, and user E is communicating with other devices and busy Information indicating that there is a user C that is not registered and is within a range where ad hoc communication is possible is displayed. When user B registers user A, user D, and user E as communication partners, the ad hoc user list display screen of user B has user A in the online state as shown in FIG. User D is communicating with another device and busy, User E is communicating with another device and busy, and unregistered user C is in ad hoc communication Information indicating that it exists in a possible range is displayed. Similarly, when the user C registers the user D and the user E as communication partners, the ad hoc user list display screen of the user C has another device as shown in FIG. The user E is communicating with other devices and is busy, and the unregistered users A and B exist in a range where ad hoc communication is possible. Information indicating that is displayed.

  In addition, on the ad hoc user list display screen, at least a user name that can be identified from the user ID and various information indicating communication information (for example, Online, Offline, Busy, Unknown, etc.) are displayed. In addition, other information can be displayed as necessary. Here, Now Playing song information is displayed on the ad hoc user list display screen together with the user name and information indicating communication information. Furthermore, information such as a text memo input by the user may be displayed on the ad hoc user list display screen as necessary.

  Information that is not displayed on the ad hoc user list display screen among various information acquired by broadcasting may be confirmed as, for example, a user information property.

  On the ad hoc user list display screen, when an unregistered user such as user C in user A, user C in user B, or user A and user B in user C is selected and determined in ad hoc mode, When a dialog is displayed with a message confirming that the registration processing is to be performed mutually, and the user accepts this, the mode shifts to the registration mode.

  FIG. 26 shows an example of user information exchanged when information communication terminals 1 held by unregistered users are mutually registered as communication partners.

  The information exchanged at the time of registration includes, for example, a device-specific ID, a profile-set User ID, and text data such as a URL of the user's own homepage or a self-introduction sentence entered by the user for registration. Image data used for a face icon (not necessarily the actual user's face photo data) displayed on the standby screen, display unit 21 during communication processing with the user Wallpaper information set by the user as the background (so-called wallpaper) pattern, user color information set by the user as the background (so-called wallpaper) display color of the display unit 21 during communication processing with the user, and communication application ( For example, IDs used in tools such as chat and IP phone) It is preferable that the ID of the messenger is included.

  Even between information communication terminals 1 held by unregistered users, it is possible to send a message to other information communication terminals existing within a communicable range. The wireless communication module 148 of the information communication terminal 1 sends, for example, a message for prompting mutual user registration to the information communication terminal 1 on the other side. The received information is transmitted to the application processor 131. The application processor 131 supplies the supplied information to the flash memory 146 connected to the application processor 131, or the flash memory 156 or the large-capacity flash memory 154 connected to the audio processor 132, and in the ad hoc mode. The information is registered as information about the information communication terminal 1 held by the user who is registered as a communication partner capable of executing file exchange or streaming.

  Information communication terminals 1 registered as communication partners capable of executing file exchange, streaming, etc. in the ad hoc mode, as shown in information communication terminals 1-4 and information communication terminals 1-5 shown in FIG. Communication is always performed one-on-one so that file exchange and streaming reproduction can be executed.

  Here, file exchange can be basically executed for all data files recorded in the information communication terminal 1, but copyright protection is applied to the data file to be exchanged. If the communication partner (file supply destination) information communication terminal 1 holds the descramble key of the data file, the data file obtained by the file exchange is opened (reproduced). I can't do it.

Further, in the streaming reproduction of the ad-hoc mode, playing a streaming content that is Gana copyrighted, the information communication terminal 1 serving as a performing streaming playback (supply destination of file), the reproduction of the stream file If permitted, the data communication file 1 obtained by file exchange, except when the information communication terminal 1 that performs streaming playback (file supply destination) holds the descramble key of the stream file. Cannot be opened (played).

  Further, during music data playback, a music data playback display screen 671 similar to that described with reference to FIG. 29 is displayed.

  When All Tracks 634 is selected on the menu screen 621 described with reference to FIG. 27, a list of all tracks recorded in the large-capacity flash memory 154 is displayed on the display unit 21.

  Content such as music data recorded in the large-capacity flash memory 154 may be acquired directly from a service provider that distributes music data or may be acquired via a predetermined recording medium. Alternatively, it may be acquired from another information communication terminal 1 or the personal computer 13. In other words, content such as music data recorded in the large-capacity flash memory 154 may be acquired using wireless communication in a WLAN ad hoc mode or infrastructure mode, or wired communication (MSC) via USB connection. Or MTP).

  In the information communication terminal 1, contents such as music data recorded in the large-capacity flash memory 154 can be recorded according to the data acquisition method, codec type, or copyright protection method. It is made like that. For example, music data, etc. when the codec format of the content such as music data is different or the copyright protection method is different depending on the service provider (group or company) that distributes the music data The content classification is synonymous with the classification based on the music data distribution source.

  Here, as an example of the classification method, it is assumed that contents such as music data are classified and recorded at least into three types of “ATRAC AD”, “Music Folder”, and “Inbox”. In such a case, when All Tracks 634 is selected on the menu screen 621 described with reference to FIG. 27, all of the three types of folders “ATRAC AD”, “Music Folder”, and “Inbox” are selected. A list of tracks is displayed on the display unit 21.

  Here, the music data stored in “ATRAC AD” and “Music Folder” is music data acquired by wireless communication (infrastructure mode or ad hoc mode), and music data stored in “ATRAC AD” The data is music data decoded in the ATRAC format, and the music data stored in the “Music Folder” is music data decoded in a format other than the ATRAC format. In addition, the music data stored in “Inbox” is music data acquired by wired communication through USB connection.

  Conventionally, copyright management methods and codec methods for obtaining (and in many cases downloading) music data for reproduction are often different depending on the service provider that distributes the music data, and the service provider that distributes the music data. In many cases, application programs for acquiring and reproducing music data are provided. In such a case, communication methods that are permitted as methods for transferring music data are also different. The information communication terminal 1 supports the ad hoc mode and infrastructure mode of WLAN, and also supports both the MSC and MTP methods of USB connection, so the corresponding application program (or software codec or DRM) By installing (protocol), music data (contents) distributed by many service providers can be acquired, stored, and played back.

  When the ATRAC AD 635 is selected on the menu screen 621 described with reference to FIG. 27, the list of tracks recorded in the “ATRAC AD” folder described above is displayed on the display unit 21, and FIG. 27 is used. When the Music Folder 636 is selected on the menu screen 621 described above, a list of tracks recorded in the “Music Folder” folder described above is displayed on the display unit 21, and the menu screen 621 described with reference to FIG. When the Inbox 638 is selected, a list of tracks received by File Transfer via USB connection and recorded in the “Inbox” folder is displayed on the display unit 21.

  In the “Inbox” folder described above, a data file acquired by making a USB connection with the personal computer 13 is stored. As described above, the music data stored in “Inbox” is music data acquired by wired communication through USB connection, and the USB connection mode may be either MSC or MTP.

  As described above, conventionally, the copyright management method and the codec method for acquiring (in many cases, downloading) music data and reproducing it are often different depending on the service provider that distributes the music data. In many cases, an application program for acquiring and reproducing music data is provided from a service provider to be distributed. That is, application programs provided by a plurality of service providers are installed in the personal computer 13, and contents such as music data stored in the personal computer 13 are handled only in predetermined application programs. May have been made possible. That is, there is a case where a copy operation of content such as music data from the personal computer 13 to the information communication terminal 1 connected via USB can be executed only in a predetermined application program. Even in such a case, since the information communication terminal 1 supports both MSC and MTP as the USB connection mode, contents such as music data provided by various service providers can be personalized. It can be acquired from the computer 13 and stored and reproduced.

  To switch the USB connection mode between MSC and MTP, for example, it is started by selecting various settings (Tools) 468 on the Home screen 451 described with reference to FIG. The setting tool of the application processor 131 includes a function of controlling the audio processor 132 based on a user operation input and switching the USB connection mode between MSC and MTP. The MSC and MTP of the audio processor 132 are included. (FIG. 13), the function used by the file exchange application or the like may be switched.

  When My Playlist 637 is selected on the menu screen 621 described with reference to FIG. 27, a list of contents such as music data created based on the user's operation input is displayed. Specifically, My Playlist is generated by classifying content such as song data recorded in three types of "ATRAC AD", "Music Folder", and "Inbox" according to a classification determined by the user. This is a list corresponding to the virtual file system that has been created. For example, the user can categorize contents such as “favorite” music into one list, categorize by genre such as “chamber music”, “orchestral music”, “instrumental music”, “voice music”, etc. `` A '', `` Musician B '', `` Orchestra A '', `` Orchestra B '', `` Conductor A '', `` Conductor B '', etc. As described above, it is possible to manage a lot of contents by classifying by composer.

  It goes without saying that My Playlist may have a hierarchical structure having a plurality of hierarchies. For example, the major categories are “composer A”, “composer B”, etc., and the middle categories are “chamber music,” “orchestral music,” “instrumental music,” “voice music,” etc. It is possible to classify by genre, classify by music name as a subcategory, and collect the same music played by a plurality of different players or orchestras in the subclass. By categorizing in this way, the user wants to listen to the “Orchestra B” of “Symphony No. X” among the “Orchestra” of “Composer A”, etc. Data can be easily searched.

  A plurality of My Playlists may be prepared. At this time, it goes without saying that the same music may be registered in multiple My Playlists, and since My Playlist is a virtual file system, the same music is registered in multiple My Playlists. However, only one data file needs to be recorded in the large-capacity flash memory 154.

  Furthermore, it can be set for each My Playlist whether or not My Playlist can be disclosed when broadcasting in the ad hoc mode. Further, only a part of the My Playlist may be set to be disclosed when the My Playlist is broadcast in the ad hoc mode.

  My Playlist can be freely created, deleted, and updated based on user operation input. For example, when information related to My Playlist is displayed, when the user presses the option button 25, it is preferable to display a dialog box for selecting processing for creating, deleting, or updating My Playlist. It is.

  FIG. 33 controls the display of the music data playback display screen 671 (FIG. 29) when Streaming 632 is selected and determined on the menu screen 621 of FIG. 27 and the music streamed from another information communication terminal 1 is being played back. It is a functional block diagram which shows the function which the menu display tool (FIG. 12) of the application processor 131 in the case of doing. Note that the menu display tool of the application processor 131 also has a function not shown in FIG. 33 and controls the display of other display screens using this function, but the description thereof is omitted here.

  The operation input acquisition unit 871 acquires a signal corresponding to a user operation input supplied from the input module 150 (FIG. 11) (acquired from the device driver via the OS).

  The registered user information acquisition unit 872 is, for example, a registered user stored in the large-capacity flash memory 154 via the audio processor 132 and registered so that music streaming and file transfer can be performed in the ad hoc mode. Alternatively, information on registered users (hereinafter referred to as registered user information) that can communicate with a plurality of application programs that perform communication processing using the WLAN infrastructure mode in the infrastructure mode is acquired (device driver via the OS). Obtained by controlling).

  The broadcast information acquisition unit 873 acquires information (hereinafter referred to as broadcast information) broadcast in the ad hoc mode described with reference to FIG. 24 received by the wireless communication module 148 (controls the device driver via the OS). To get it).

  The public playlist acquisition unit 874 acquires the public playlist transmitted from the information communication terminal 1 that is the streaming supply source received by the wireless communication module 148.

  The display control unit 875 is acquired by the registered user information from the registered user information acquisition unit 872, the broadcast information from the broadcast information acquisition unit 873, and the public playlist acquisition unit 874 in response to an operation input from the operation input acquisition unit 871. Based on the published playlist, for example, a display screen related to the streaming operation such as the ad hoc user list screen 681 shown in FIG. 30 is generated, and the display module 142 is controlled (device driver is controlled via the OS). To be displayed on the display unit 21.

  Next, referring to the flowchart of FIG. 34, the operation of the menu display tool of the application processor 131 when Streaming 632 is selected and determined on the menu screen 621 of FIG. 27 and streaming is performed from another information communication terminal 1 will be described.

  In step S <b> 2, the registered user information acquisition unit 872 reads out information related to registered users for mutual communication in the ad hoc mode from the large-capacity flash memory 154 via, for example, the audio processor 132, and supplies the information to the display control unit 875. To do.

  In step S <b> 3, the broadcast information acquisition unit 873 determines whether or not broadcast information has been received from another information communication terminal 1, and determines that broadcast information has been received from the other information communication terminal 1. If so, the process proceeds to step S4. If it is determined in step S3 that broadcast information has not been received, the processes in steps S4 and S5 are skipped, and the process proceeds to step S6 described later.

  In step S4, the broadcast information acquisition unit 873 supplies the acquired information to the display control unit 875. The display control unit 875 determines whether the registered users of the mutual communication in the ad hoc mode are online or offline based on the registered user information and the broadcast information.

  In step S5, the broadcast information acquisition unit 873 extracts information broadcast from a non-registered user from the information acquired by broadcast based on the registered user information and the broadcast information, and the display control unit 875.

  In step S6, the display control unit 875 displays a list of information about the user as shown in FIG. 30, for example, based on the determination result in step S4, the information supplied in step S5, registered user information, or broadcast information. The displayed ad hoc user list display screen 681 is generated and displayed on the display unit 21.

  Next, in step S7 in this case, one of the online registered user information (for example, “User B”) displayed on the ad hoc user list display screen 681 is selected and determined, and this is indicated by the operation input acquisition unit. When notified to the public list acquisition unit 874 from 871, in step S8, the public playlist acquisition unit 874 acquires the public playlist set by the user B and received by the ad hoc communication engine executed in the application processor 131. And supplied to the display control unit 875.

  When any one of the information on the online registered user displayed on the ad hoc user list display screen 681 (for example, “User B”) is selected and determined, the ad hoc communication engine executed in the application processor 131 is the user B. A streaming connection with the information communication terminal 1 is established, and a public playlist is acquired.

  In step S9, the display control unit 875 displays the public playlist as shown in FIG. 31 based on the public playlist acquired in step S8 and the Now Playing information of the broadcast information from the information communication terminal 1 of the selected user. A Playlist list display screen 701 is generated and displayed on the display unit 21.

  In step S10, the display control unit 875 determines whether or not the music has been selected and determined based on the operation input supplied from the operation input acquisition unit 871, and if it is determined that the music has been selected and determined, the process proceeds to step S11. move on.

  For example, when Now Playing shown in FIG. 31 is selected or determined, or music data included in the public playlist shown in FIG. 32 displayed as a result of selecting and determining a predetermined public playlist, in other words, If a predetermined music track is selected and determined from the track display screen 711 displaying a list of music tracks, the process proceeds to step S11.

  In step S11, a predetermined display process is performed. The details of this process are shown in the flowchart of FIG. At this time, the music data in the application program 131 is exchanged with the information communication terminal 1 that is the streaming supplier, and the streaming reproduction is started.

  In step S21, the display control unit 875 extracts user color information and wallpaper information (FIG. 26) of the streaming supply source from the registered user information, and text memo information from the broadcast information (FIG. 24) from the streaming supply source. Extract.

  In step S22, for example, as shown in FIG. 36, the display control unit 875 displays the content introduction information display area 671A in which the background color is a color based on the user color information of the streaming supply source, and the text ( For example, a music data reproduction display screen 671 composed of a content reproduction information display area 671B on which a user name (XXXX in the figure) is further displayed is generated and displayed on the display unit 21.

  In step S23, the display control unit 875 determines whether or not there is a command to change the display screen based on the operation input supplied from the operation input acquisition unit 871, and when it is determined that there is such a command, Proceed to step S24.

  In step S24, the display control unit 875 determines whether or not the display screen change command is a command to change from the other display screen to the music data reproduction display screen 671, and is not such a command. If determined, the process proceeds to step S25.

  In step S25, the display control unit 875 generates a display screen according to the command so that the wallpaper based on the wallpaper information of the streaming supply source extracted in step S21 is displayed, and causes the display unit 21 to display the display screen.

  For example, when the music data playback display screen 671 shown in FIG. 36 is displayed, when the HOME button 23 is operated, the wallpaper based on the streaming source wallpaper information is displayed as shown in FIG. A HOME screen 451 is displayed.

  Thereafter, the process returns to step S23, and the subsequent processing is similarly performed.

  If it is determined in step S24 that the display is changed from the other display screen to the music data playback display screen 671, for example, the BACK button 24 is operated after the HOME screen 451 is displayed in the processing of the previous step S25. If it is, the process returns to step S22, the subsequent processing is performed, and the music data reproduction display screen 671 (FIG. 36) corresponding to the streaming supply source is displayed.

  If it is determined in step S23 that there is no instruction to change the display screen, the process proceeds to step S26, where it is determined whether or not the streaming has ended. If it is determined that the streaming has not ended, the process returns to step S23. Subsequent processing is similarly performed.

  If it is determined in step S26 that streaming has ended, the process returns to FIG. 34 and the process ends.

  If it is determined in step S10 that the music has not been selected and determined, the process proceeds to step S12, where it is determined whether or not the streaming has ended. If it is determined that the music has not ended, the process returns to step S10 and thereafter. These processes are performed in the same manner.

  If it is determined in step S12 that the streaming has ended, this display process ends.

  As described above, display processing during streaming is performed. The display process when music is played back other than streaming playback is as shown in the flowchart of FIG.

  That is, for example, as described with reference to FIG. 28, when the search result (music name) selected by the cursor 663 is selected and determined using the determination button 27, the reproduction of the music is started. The display process shown below is started.

  In step S31, own User Color information and wallpaper information stored as registered user information stored in the large-capacity flash memory 154 are acquired.

  In step S32, for example, as shown in FIG. 29, a content introduction information display area 671A in which the background color is a color (colorless in the example of FIG. 29) based on the user color information acquired in step S31, The music data reproduction display screen 671 including the content reproduction information display area 671B on which the information is displayed is generated and displayed on the display unit 21.

  In step S33, it is determined whether or not there is a command to change the display screen. If it is determined that there is such a command, the process proceeds to step S34.

  In step S34, it is determined whether or not the display screen change command is a command to change from another display screen to the music data reproduction display screen 671. If it is determined that the command is not such a command, Proceed to step S35.

  In step S <b> 35, a display screen corresponding to the command is generated so that the wallpaper based on the wallpaper information acquired in step S <b> 31 is displayed and displayed on the display unit 21.

  For example, when the music data playback display screen 671 shown in FIG. 29 is displayed and the HOME button 23 is operated, as shown in FIG. 14, wallpaper based on own wallpaper information (in the case of the example of FIG. 14) , Plain wallpaper) is displayed, and the HOME screen 451 is displayed.

  Thereafter, the process returns to step S33, and the subsequent processing is similarly performed.

  If it is determined in step S34 that the display is changed from the other display screen to the music data playback display screen 671, for example, the BACK button 24 is operated after the HOME screen 451 is displayed in the processing of the previous step S35. If it is, the process returns to step S32, the subsequent processing is performed, and a predetermined music data reproduction display screen 671 (FIG. 29) is displayed.

  If it is determined in step S33 that there is no command to change the display screen, the process proceeds to step S36, where it is determined whether the reproduction has been completed. If it is determined that the reproduction has not been completed, the process returns to step S33. Subsequent processing is similarly performed.

  If it is determined in step S36 that the reproduction has ended, the process ends.

  That is, during streaming playback, unlike other playback cases, the content introduction information display area 671A is displayed in a color corresponding to the streaming supply source (FIG. 36), and screens other than the music data playback display screen 671 are displayed. When displayed, the wallpaper is displayed so as to be provided by the streaming supplier (FIG. 37), so that the display screen during streaming playback can be varied. it can.

  In streaming playback, information (for example, a user name) related to a streaming supply source is displayed in, for example, the content playback information display area 671B. Therefore, the streaming supply source is displayed together with the background color of the content introduction information display area 671A. The user can be notified of who is.

  In the above, the display screen corresponding to the streaming supply source is displayed at any time during streaming playback, but only when the currently playing music is streamed at the streaming supply source. Such a display screen can be displayed.

  In this case as well, basically the same processing as the processing shown in FIG. 34 is performed, but in the display processing in step S11 in this case, the processing shown in the flowchart of FIG. 39 is performed.

  That is, in step S51, the display control unit 875 determines whether or not Now Playing on the public playlist list display screen 701 in FIG. 31 has been selected and determined based on the operation input from the operation input acquisition unit 871. If it is determined that the selection has been determined, in step S52, processing similar to the display processing shown in FIG. 35 is performed. As a result, a display screen corresponding to the streaming supplier is displayed. In this way, when the music currently being played is streamed at the streaming supply source, a display screen corresponding to the streaming supply source is displayed.

  On the other hand, when Now Playing is not selected and determined in step S51, that is, when a predetermined public playlist is selected and determined, and music data included in the public playlist shown in FIG. 32 displayed as a result is selected and determined. In step S53, basically, display processing similar to the display processing shown in FIG. 38 is performed. As a result, when music other than the music currently being played is streamed at the streaming supply source, a predetermined display screen determined in advance is displayed.

  In this case, in the process corresponding to step S36 shown in FIG. 38, the reproduction end determination process is performed instead of the reproduction end determination process.

  In the above description, the case where music is streamed has been described as an example. However, the present invention can also be applied to the case where other content is streamed.
